Henrik Ibsen, the Royal Palace & Oslo's Historic Centre

Oslo's historic centre (Karl Johans gate — the main street of Oslo, running 1.6 km from Oslo Central Station (Oslo S) west to the Royal Palace (Slottet), lined with the National Theatre, the Parliament (Stortinget), the University of Oslo, and the Cathedral): Oslo was established as the capital of Norway in 1814 (when Norway became independent from Denmark and established its constitution at Eidsvoll — the most important event in Norwegian history), and the historic centre was planned in the early 19th century in the Neoclassical style on the grid pattern of the new Norwegian capital.
